Referring to FIGS. 1-2, the display assembly 400 may include a cover plate 402 and a display 404. The display 404 is embedded in the front case 202. The cover plate 402 covers the display 404 for protecting the display 404. The cover 402 may be made of a light-transmissive material such as glass, plastic, or the like. The display 404 includes a display area 401 and a non-display area 403. The non-display area 403 is arranged on a side of the display area 401, or enclosing a periphery of the display area 401.
The camera assembly 600 may be disposed on a back side of the mobile phone as a rear camera.

Of course, the camera assembly 600 may also be arranged at other positions such as an upper middle or upper right position of the rear cover 204 according to specific needs, which is not limited herein. In particular, a projection of the camera assembly 600 on the display 404 may be disposed within the display area 401 of the display 404.
It shall be understood that orientations or position relationships indicated by terms of “up”, “down”, “left”, “right”, etc. herein and hereinafter are based on orientations or position relationships shown in the drawings only for the purpose of facilitating and simplifying the description. They do not indicate or imply that the devices or components referred to must have a particular orientation, be constructed or operated in a particular orientation, which are therefore not to be construed as a limitation of the present disclosure.
As shown in FIG. 5, in some embodiments, the camera assembly 600 may include a first camera module 100, a second camera module 300, a decorating member 700, and a bracket 900. The first camera module 100 is a periscopic telephoto camera module. The second camera module 300 is a wide-angle camera module. The first camera module 100 and the second camera module 300 are arranged side by side. The first camera module 100 and the second camera module 300 may also be an integrated camera module.
It is to be noted that the terms of “first”, “second”, etc. herein and hereinafter are for descriptive purposes only. They are not to be construed as indicating or implying relative importance or implicitly indicating a number of technical features. Accordingly, a feature that qualifies as “first”, “second”, etc. may explicitly or implicitly include one or more of the described features.
Further, as shown in FIGS. 6 to 9, the first camera module 100 is a periscopic camera module. Compared to a vertical camera module, the periscopic camera module may be configured to change a light propagation path requiring less height of the camera module, which may reduce an overall thickness of the electronic device. Specifically, the first camera module 100 may include elements such as a fixing member 10, a rotating member 20 disposed on and rotatable relative to the fixing member 10, a ball 30, a connecting member 40 disposed between the fixing member 10 and the rotating member 20, a drive mechanism 50, a magnetic member 60, a lens assembly 70, and an image sensor 80.
The connecting member 40 is disposed between the fixing member 10 and the rotating member 20. The connecting member 40 is position-limited via the magnetic member 60 to the fixing member 10, the connecting member 40 and the rotating member 20. The ball 30 includes a first ball 32 and a second ball 34. The first ball 32 is disposed between the rotating member 20 and the connecting member 40. The second ball 32 is disposed between the connecting member 40 and the fixing member 10. After entering the first camera module 100, an incident light is redirected via the rotating member 20 and then transmitted via the lens assembly 70 to the image sensor 80. The light is sensed by the image sensor 80.
The fixing member 10 is configured to connect, carry, fix, etc. other elements of the first camera module 100, fixedly connected with other parts of the phone. In this way, the first camera module 100 is arranged integrally in the phone. Specifically, the fixing member 10 may be a mounting bracket on which other elements of the first camera module 100 are directly or indirectly mounted. Or, the fixing member 10 may be a shell, such as a box-shaped shell with a capacitive space, in which other elements of the first camera module 100 are accommodated.
Specifically, the fixing member 10 may include a top wall 13, a plurality of side walls 14 connected to the top wall 13, and a bottom wall 15 facing the top wall 13. The top wall 13, the plurality of side walls 14, and the bottom wall 15 enclose a capacitive space to accommodate the rotating member 20. In the embodiments, a number of the side walls 14 is four. In other embodiments, one or both of the top wall 13 and the bottom wall 15 may be omitted and only two side walls 14 are required.
Further, as shown in FIG. 6, the top wall 13 is defined with a light inlet 13 a. An external light may enter the first camera module 100 through the light inlet 13 a. Further, a groove 13 b running through or not through the top wall 13 is defined on the top wall 13 at opposite sides of the light inlet 13 a. The groove 13 b may be achieved by stamping or the like. The groove 13 b matches the decorating member 700 at least partially. It should be noted that a position of the groove 13 b is not limited to the two sides of the light inlet 13 a, but may also be curved and enclosed around an entire periphery of the light inlet 13 a, or on the side walls 14 of the fixing member 10, or at other positions.
Further, as shown in FIGS. 7 and 10, the side wall 14 of the fixing member 10 may include a first side wall 140, a second side wall 142 connected perpendicularly to the first side wall 140, a third side wall 144 disposed parallel to the second side wall 142, and a fourth side wall 146 connected perpendicularly to the second side wall 142 and the third side wall 144 and disposed parallel to the first side wall 140. The first side wall 140 is disposed on a side of the connecting member 40 away from the rotating member 20, and are all connected perpendicularly to the second side wall 142 and the third side wall 144. The fourth side wall 146 is defined with an opening, such that the incident light may be transmitted to other parts through the opening after redirecting and other operations.
The bottom wall 15 is arranged parallel and facing the top wall 13 and connected to a side of the first side wall 140, the second side wall 142, the third side wall 144, and the fourth side wall 146 away from the top wall 13, respectively.
Further, a number of side walls 14 of the fixing member 10 may be two. The side walls 14 are connected and arranged on opposite sides of the top wall 13. In some embodiments, a number of the grooves 13 b is two. Each of the grooves 13 b is arranged at a connection of the top wall 13 and the side walls 14 on opposite sides of the light inlet 13 a. Specifically, the grooves 13 b are both configured in a long strip in parallel, as shown in FIG. 6.
As shown in FIGS. 6 and 7, the rotating member 20 may include a base 22 and a light redirecting member 24.
The base 22 may include a first side wall 221, a second side wall 222 connected to the first side wall 221, a third side wall 223 disposed parallel to the second side wall 222 and connected to the first side wall 221, a bottom wall 224 connected to the first side wall 221, the second side wall 222 and the third side wall 223, and a guide plate 225 disposed in a space enclosed by the first side wall 221, the second side wall 222, the third side wall 223 and the bottom wall 224. The first side wall 221 is disposed on a side of the base 22 near the connecting member 30. The second side wall 222 is facing to the second side wall 142 of the fixing member 10 and is connected to on a side of the first side wall 221. The third side wall 223 is facing the third side wall 144 of the fixing member 10 and is connected to the other side of the first side wall 221. The bottom wall 224 of the base 22 is facing the bottom wall 15 of the fixing member 10 and is connected to a side of the first side wall 221, the second side wall 222 and the third side wall 223 near the bottom wall 15 of the fixing member 10, respectively. The guide plate 225 is arranged extending from the first side wall 221 in a direction away from the first side wall 140 of the fixing member 10. The guide plate 225 is arranged with an inclined surface 225 a relative to the bottom wall 224. A number of the guide plates 225 may be one or more, and the one or more inclined surfaces 225 a formed may be configured to support the light redirecting member 24.
The light redirecting member 24 is fixedly mounted on the base 22 and corresponds to the light inlet 13 a of the fixing member 10 for receiving the incident light entering from the light inlet 13 a, to steer the incident light. Specifically, the light redirecting member 24 may be fixed to the inclined surface 225 a at the guide plate 225 of the base 22 by means of adhesive bonding or the like. In this way, the light redirecting member 24 and the base 22 may rotate synchronously relative to the fixing member 10. The light redirecting member 24 may be an element capable of changing the light propagation direction through reflection, refraction, etc., such as a flat mirror, prism, etc.
In cases of the light redirecting member 24 as a prism, as shown in FIG. 11, the light redirecting member 24 may be a triple prism. The triple prism may include a light incident surface 240, a light reflecting surface 242, and a light emitting surface 244. Specifically, the light incident surface 240 corresponds to the light inlet 13 a of the fixing member 10 and is connected in sequence with the light reflecting surface 242 and the light emitting surface 244. A cross-section of the light incident surface 240, the light reflecting surface 242 and the light emitting surface 244 may be an isosceles right-angled triangle. Specifically, the light reflecting surface 242 is configured to be tilted at a 45-degree relative to the light incident surface 240 and the light emitting surface 244, i.e., an angle α between the two is 45 degrees. It should be noted that a degree of tilt of the inclined surface 225 a of the guide plate 225 is consistent with that of the light reflecting surface 242. In this way, the light redirecting member 24 is fixed to the base 22 through a matching of the light reflecting surface 242 and the inclined surface 225 a of the guide plate 225. Further, the light incident surface 240 and the light emitting surface 244 are perpendicular to each other. An incident light enters from the light incident surface 240 after passing through the light inlet 13 a, and is further emitted from the light emitting surface 244 after being reflected and redirected by the light reflecting surface 242. It is understood that the incident light may also be emitted from the opening of the fourth side wall 146 of the fixing member 10 after refraction through the triple prism.
As shown in FIG. 12, the light redirecting member 24 may also be a quadruple prism. In addition to the above-mentioned the light incident surface 240, the light reflecting surface 242 and the light emitting surface 244 of the triple prism, the quadruple prism further includes a backlight surface 246 connected to and disposed between the light reflecting surface 242 and the light emitting surface 244 and disposed parallel to the light incident surface 240 back-to-back. A distance range between the backlight surface 246 and the light incident surface 240 may be 4.8-5.0 mm, specifically such as 4.8 mm, 4.85 mm, 4.9 mm, 4.95 mm, 5.0 mm, and the like. The light redirecting member 24 formed from the light incident surface 240 and the backlight surface 246 configured based on the distance range is moderately sized to fit well into the first camera module 100. In this way, a more compact and miniaturized first camera module 100, camera assembly 600 and electronic device to meet more consumer needs.
It should be noted that, to a certain extent, the quadruple prism may be equivalent to a prism formed by excising a portion of the corner angle consisting of the light reflecting surface 242 and the light emitting surface 244 of the above-mentioned triple prism. It is to be specified that, as shown in FIGS. 13 and 14, due to the need for incident light, the light reflecting surface 242 is configured to be tilted relative to the horizontal direction in practical applications. The light redirecting member 24 is asymmetrically structured in a direction in which the light is reflected by the light reflecting surface 242, such that an actual optical area of a side of the light reflecting surface 242 away from the light inlet 13 a is smaller than that of a side near the light inlet 13 a. In this way, a portion of the light reflecting surface 242 away from the light inlet 13 a reflects only less or even no light. That is, the portion makes very little or no contribution to the reflection of the light. As for the light redirecting member 24 of the quadruple prism, compared to that of the triple prism, the corner angle of the triple prism away from the light inlet 13 a is excised, such that a thickness of the light redirecting member 24 in a direction perpendicular to the light incident surface 240 is reduced without affecting a redirecting effect of the light redirecting member 24 on the incident light. In this way, a lightening and thinning and miniaturization of the first camera module 100 may be reduced. Due to the backlight surface 246, the light redirecting member 24 is further arranged to be fixed to the base 22 via the backlight surface 246, thereby providing a stronger and more stable fixation between the light redirecting member 24 and the base 22.
It should be noted that the above description is not intended to restrict the structure of the light redirecting member 24. For example, the light reflecting surface 242 may also be tilted at other degrees relative to the light incident surface 240, such as 30 degrees, 60 degrees, etc. The light incident surface 240 and the light emitting surface 244 may not be configured vertically, such as tilted at 80 degrees, 90 degrees, etc. The backlight surface 246 may not be parallel to the light incident surface 240. Configurations are not limited as long as the light redirected by the light redirecting member 24 is received by the lens assembly 70.
Further, the prism may be made of a light-transmitting material such as glass or plastic. A reflective material such as silver may be coated on a surface of the light reflecting surface 242 of the prism to enhance the reflection of the incident light. Further, in cases of the prism being made of a brittle material such as glass, a hardening layer may be formed on surfaces of the incident light surface 240, the light reflecting surface 242, the light emitting surface 244, and the backlight surface 246, etc. by hardening the prism, thereby improving a strength of the light redirecting member 24. The hardening treatment may be infiltrating lithium ions or applying films to each surface of the prism without affecting the light conversion of the light redirecting member 24.
It is further noted that a number of the light redirecting members 24 may be one. After once redirected by the light redirecting member 24, the incident light reaches the image sensor 80 by transmission of the lens assembly 70. Of course, the number of the light redirecting members 24 may also be more than one. The incident light may reach the image sensor 80 by transmission of the lens assembly 70 after a plurality of times of redirecting by the light redirecting member 24. The image sensor 80 may be arranged according to actual needs and is not specifically limited herein.
Further, as shown in FIG. 7, the ball 30 may include a first ball 32 and a second ball 34. A number of the first ball 32 and that of the second ball 34 are both two. The first ball 32 and the second ball 34 may be of a same shape, size, and material. Centers of the two first balls 32 are located on a first axis A1. Centers of the two second balls 34 are located on a second axis A2. In this way, the first ball 32 may rotate around the first axis A1 by self-rotation and the second ball 34 may rotate around the second axis A2 by self-rotation. The first axis A1 and the second axis A2 may be perpendicular to each other, with the first axis A1 being perpendicular to the light incident surface 240 and the second axis A2 being parallel to the light incident surface 240 and the light reflecting surface 242. The first axis A1 and the second axis A2 may further both be perpendicular to an optical axis A3 of the lens assembly 70 (as shown in FIG. 8). It is to be noted that the number of the first balls 32 and that of the second balls 34 are not limited to two, but may also be one or three or more than three, etc. The number of the first balls 32 and that of the second balls 34 may be equal or unequal, and may be configured according to actual needs.
Further, as shown in FIG. 7, the connecting member 40 may be disposed between the fixing member 10 and the rotating member 20. In cases of the fixing member 10 as a shell, the connecting member 40 may be disposed between the first side wall 140 of the fixing member 10 and the rotating member 20. Specifically, the connecting member 40 is a plate including a first outer wall surface 42 and a second outer wall surface 44 disposed back to back. The first outer wall surface 42 is facing the first side wall 221 of the base 22. The second outer wall surface 44 is facing the first side wall 140 of the fixing member 10.
Further, as shown in FIGS. 9, 15 and 16, the first side wall 221 of the base 22 is defined with a first rotation slot 221 a matched to the first ball 32 for accommodating at least part of the first ball 32. The first outer wall 42 of the connecting member 40 is defined with a second rotation slot 42 a facing the first rotation slot 221 a and matched to the first ball 32 for accommodating at least part of the first ball 32. In an assembled state, a part of the first ball 32 is accommodated in the first rotation slot 221 a and another part is accommodated in the second rotation slot 42 a such that the rotating member 20 may rotate around the first axis A1 (as shown in FIG. 7) within a range defined by a first gap D1 by the rotation of the first ball 32 in the first rotation slot 221 a and the second rotation slot 42 a.
It should be noted that a number of the first rotation slot 221 a and that of the second rotation slot 42 a correspond to the number of the first balls 32. In cases of the number of the first balls 32 being two, the number of the first rotation slot 221 a and that of the second rotation are also both two. Specifically, both the first rotation slot 221 a and the second rotation slot 42 a may be shaped as a part of a sphere. A radius of the sphere is greater than the radius of the first ball 32, and wherein the relative distance between the first rotation slot 221 a and the second rotation slot 42 a along the direction perpendicular to the first axis A1 is less than the diameter of the first ball 32 to enable the first ball 32 to accommodate the first rotation slot 221 a and the second within the rotation slot 42 a and forms a first gap D1 between the first sidewall 221 of the seat 22 and the first outer wall surface 42 of the rotating member 20. In an application scenario, the first and second rotation slots 221 a and 42 a have the same shape and are axially symmetrical in the direction of the first axis A1, as shown in FIG. 9; in another application scenario, as shown in FIG. 17, the first rotation slot 221 a and the second The rotating slots 42 a have different shapes, but are also all part of a sphere.
Further, as shown in FIGS. 18 to 20, the second outer wall surface 44 of the connecting member 40 is defined with a third rotation slot 44 a matched to the second ball 34 for accommodating at least part of the second ball 34. The first side wall 140 of the fixing member 10 is defined with a fourth rotation slot 140 a facing the third rotation slot 44 a and matched to the second ball 34 for accommodating at least part of the second ball 34. In an assembled state, a part of the second ball 34 is accommodated in the third rotation slot 44 a and another part is accommodated in the fourth rotation slot 140 a, such that the rotating member 20 and the connecting member 40 may rotate around the second axis A2 (as shown in FIGS. 7 and 9) within a range defined by a second gap D2 by the rotation of the second ball 34 in the third rotation slot 44 a and the fourth rotation slot 140 a.
It should be noted that a number of the third rotation slot 44 a and that of the fourth rotation slot 140 a correspond to the number of the second ball 34. In cases of the number of the second ball 34 being two, the number of the third rotation slot 44 a and that of the fourth rotation slot 140 a are also both two. Specifically, both the third rotation slot 44 a and the fourth rotation slot 140 a may be shaped as a part of a sphere. A radius of the sphere is larger than that of the second ball 34. A relative distance between the third rotation slot 44 a and the fourth rotation slot 140 a along a direction perpendicular to the second axis A2 is less than a diameter of the second ball 34. In this way, the second ball 34 may be accommodated in the third rotation slot 44 a and the fourth rotation slot 140 a. The second gap D2 may be defined between the first side wall 140 of the fixing member 10 and the second outer wall surface 44 of the connecting member 40. Similar to the shapes of the first rotation slot 221 a and the second rotation slot 42 a, the shape of the third rotation slot 44 a and that of the fourth rotation slot 140 a may be same or different, and are not specifically limited herein.
It should be understood that the mobile phone may vibrate to a certain extent due to environmental factors during the process of taking pictures, and the fixing member 10 in the first camera module 100 may be driven to shake. In this way, a certain deviation in an incidence position of the external light, etc. may be caused, and thus the capture and imaging of the light may be adversely affected. In the embodiments, the first ball 32 is arranged between the rotating member 20 and the connecting member 40, and the second ball 34 is arranged between the connecting member 40 and the fixing member 10, such that the rotating member 20 may rotate around the first axis A1 and/or the second axis A2 relative to the fixing member 10. The rotating member 20 may move in opposite directions relative to the fixing member 10 in the direction of the first axis A1 and the second axis A2 perpendicular to each other as well as in the direction perpendicular to the first axis A1 and the second axis A2. In this way, an incidence deviation of the incident light entering from the light inlet 13 a due to the shaking of the fixing member 10 may be compensated to keep the optical path stable, and to improve the image quality of the first camera module 100. Moreover, the ball 30 is arranged such that the rotating member 20 may be rotationally connected with the fixing member 10, which can reduce an influence of friction on the rotation of the rotating member 20 due to a small contact area. In this way, a precision of the rotation of the rotating member 20 may be improved, thereby further improving the imaging quality. In addition, the rotating member 20 may rotate around the first axis A1 and/or the second axis A2, and a motion in the direction of the first axis A1 and the second axis A2 as well as in the direction perpendicular to the first axis A1 and the second axis A2 may be thus achieved. Compared to moving directly in a corresponding direction, a space occupied by the rotating member 20 in the direction of the first axis A1 and the second axis A2 during movement may be reduced, thereby reducing a volume of the entire first camera module 100.
Further, a vibration of the electronic device may be monitored by a gyroscope, an accelerometer, etc. arranged in the mobile phone. The drive mechanism 50 may be controlled to drive the rotating member 20 to rotate based on a detected results. Specifically, as shown in FIG. 7, the drive mechanism 50 includes a first drive mechanism 52 and a second drive mechanism 54. The first drive mechanism 52 is configured to drive the rotating member 20 to rotate around the first axis A1 relative to the fixing member 10 via the first ball 32. The second drive mechanism 54 is configured to drive the rotating member 20 to rotate around the second axis A2 relative to the fixing member 10 via the second ball 34.
The first drive mechanism 52 may be an electromagnetic drive mechanism, specifically including a first magnet 520 and a first coil 522. A first mounting slot 222 a is defined on the second side wall 222 of the base 22. The first magnet 520 may be fixed in the first mounting slot 222 a by means of an adhesive or the like. The first coil 522 corresponds to the first magnet 520 and is arranged on the second side wall 142 of the fixing member 10. When the first coil 522 is energized, the first magnet 520 may undergo a movement to drive the base 22 to rotate the light redirecting member 24 around the first axis A1.
Further, as shown in FIGS. 6 and 10, the first drive mechanism 52 may also include a second magnet 524 and a second coil 526. A second mounting slot 223 a is defined on the third side wall 223 of the base 22. The second magnet 524 may be fixed in the second mounting slot 223 a by means of an adhesive or the like. The second coil 526 corresponds to the second magnet 524 and is arranged on the third side wall 144. When the second coil 526 is energized, the second magnet 524 may undergo a movement to drive the base 22 to rotate the light redirecting member 24 around the first axis A1 (as shown in FIG. 7).
It should be noted that the rotation of the rotating member 20 around the first axis A1 may be achieved either through driving the base 22 separately by the first magnet 520 and the first coil 522 or the second magnet 524 and the second coil 526, or through driving the base 22 jointly on both sides of the base 22.
Further, as shown in FIG. 7, the second drive mechanism 54 may also be an electromagnetic drive mechanism, which may include a third magnet 540 and a third coil 542. A third mounting slot 224 a is defined on the bottom wall 224 of the base 22. The third magnet 540 may be fixed in the third mounting slot 224 a by means of an adhesive or the like. The third coil 542 corresponds to the third magnet 540 and is arranged on the bottom wall 15 of the fixing member 10. When the third coil 542 is energized, the third magnet 540 may undergo a movement to drive the base 22 to drive the light redirecting member 24 around the second axis A2.
It is to be noted that the first drive mechanism 52 and the second drive mechanism 54 are not limited to the above-mentioned electromagnetic implementation. For example, both may also be piezoelectric drive mechanisms or memory alloy drive mechanisms and the like.
The piezoelectric drive mechanism may be based on an inverse piezoelectric effect of piezoelectric ceramic materials. When a voltage is applied to the piezoelectric material, the piezoelectric material generates mechanical stress, which is then transformed into mechanical deformation. In this way, the mechanical deformation of the piezoelectric material may be controlled by controlling the voltage applied to the piezoelectric material, thereby generating rotation to drive the base 22. The driving method has advantages of simple structure and low speed. While the memory alloy drive mechanism may be based on characteristics of the shape memory alloy. That is, once the shape memory alloy has memorized any shape, even if deformation occurs, it can still return to the shape before deformation when heated to a certain appropriate temperature, so as to achieve the purpose of driving. The driving method has advantages of rapid dislocation and free direction. In actual production and assembly, different drive mechanisms can be used depending on needs.
Further, as shown in FIGS. 9 and 18, the magnetic member 60 may include a first magnetic member 62 and a second magnetic member 64. The first magnetic member 62 may include a fourth magnet 620 and the second magnetic member 64 may include a fifth magnet 640. A fourth mounting slot 221 b matching the fourth magnet 620 is defined on the first side wall 221 of the base 22. The fourth magnet 620 may be fixed in the fourth mounting slot 221 b by means of an adhesive or the like. The first side wall 140 of the fixing member 10 is defined with a fifth mounting slot 140 b. The fifth mounting slot 140 b corresponds to the fourth mounting slot 221 b and matches the fifth magnet 640, such that the fifth magnet 640 may be fixed in the fifth mounting slot 140 b by means of an adhesive or the like. It should be noted that the polarity of the magnetic pole on a side of the fourth magnet 620 facing the fifth magnet 640 is opposite to the polarity of the magnetic pole on a side of the fifth magnet 640 facing the fourth magnet 620. In this way, the fourth magnet 620 and the fifth magnet 640 may positional limit the base 22 holding the fourth magnet 620, the fixing member 10 holding the fifth magnet 640, and the connecting member 40 disposed between the fourth magnet 620 and the fifth magnet 640 by means of an anisotropic phase attraction.
In the above embodiments, the base 22, the connecting member 40 and the fixing member 10 are positional limited within a certain range, such that the three need not be bound together by a direct connection structure. In this way, when the rotating member 20 rotates around the first axis A1 or the second axis A2 relative to the fixing member 10, the fixing member 10, the connecting member 40 and the base 22 do not disperse, thereby reducing the friction generated during the rotation of the rotating member 20 and making the rotation more precise.
The rotation of the rotating member 20 of the above embodiments relative to the rotation of the fixing member 10 around the first axis A1 and the second axis A2 is achieved through the rotation of the first ball 32 and the second ball 34 and the coordination between the connecting member 40 and the fixing member 10 and the rotating member 10. In some embodiments, the rotation of the rotating member 20 around the first axis may be achieved by means of a guide rail disposed on the fixing member 10 without the need for the connecting member, the first ball, the second ball, and other elements.
For example, the first camera module 100 may include elements such as the fixing member 10, the rotating member 20 disposed on the fixing member 10 and rotatable relative to the fixing member 10, the drive mechanism 50, the lens assembly 70, and the image sensor 80. The drive mechanism 50, the lens assembly 70, the image sensor 80 and other elements may be the same as those of the above-mentioned embodiments. Specifically, as shown in FIGS. 21 and 22, in some embodiments, the guide rail may be an arcuate rail 152 disposed on the bottom wall 15 of the fixing member 10. A bottom surface of the bottom wall 224 of the base 22 may be an arcuate bottom surface 226. The arcuate bottom surface 226 matches the arcuate rail 152, i.e., a central axis of the arcuate bottom surface 226 coincides with that of the arcuate rail 152. In this way, a coordination of the rotating member 20 and the base 22 is more compact and the rotating member 20 may move along the arcuate rail 152 driven by the drive mechanism 50, thereby enabling the rotating member 20 to rotate around the central axis of the arcuate rail 152. In the embodiments, the first axis A1 is the central axis of the arcuate rail 152.
As shown in FIGS. 23 and 24, in some embodiments, the guide rail may also be an arcuate recess 14 a defined on the second side wall 142 and the third side wall 144 of the fixing member 10. The second side wall 222 and the third side wall 223 of the base 22 of the embodiments are arranged with a slider 227. The slider 227 is mounted in the arcuate recess 14 a and may be driven to move along the arcuate recess 14 a by the drive mechanism 50, such that the rotating member 20 may rotate around the central axis of the arcuate recess 14 a. In the embodiments, the first axis A1 is the central axis of the arcuate recess 14 a.
It should be noted that the central axis of the arcuate rail 152 and that of the arcuate recess 14 a in the above embodiments may be inside or outside the fixing member 10.
It should be further noted, referring together to FIGS. 6, 8, 25, and 26, that the lens assembly 70 is movably disposed within a capacitive space defined by the fixing member 10, and is disposed on a side of the light emitting surface 244 of the light redirecting member 24 to receive and transmit light redirected by the light redirecting member 24. Since the lens assembly 70 may move within the capacitive space defined by the fixing member 10, the lens assembly 70 is capable of adjusting a distance between the lens assembly 70 and the light emitting surface 244 of the light redirecting member 24, thereby enabling a focusing or zooming of the first camera module 100.
Specifically, the lens assembly 70 may include a moving member 72, a lens unit 74, and a third drive mechanism 76. The lens unit 74 may be fixed to the moving member 72, and an optical axis of the lens unit 74 is the optical axis A3 of the lens assembly 70 described above. The third drive mechanism 76 connects the fixing member 10 and the moving member 72. The third drive mechanism 76 is configured to drive the moving member 72 in a direction of the optical axis of the lens unit 74.
In some embodiments, the lens unit 74 may include a plurality of lenses 740 arranged side by side. Optical axes of the plurality of lenses 740 may all disposed in a same line and act as the optical axis of the lens unit 74.
The moving member 72 may have a substantially cylindrical shape, as shown in FIG. 8. The plurality of lenses 740 may be spaced in the moving member 72 along a moving direction of the moving member 72 (i.e., the direction of the optical axis A3 of the lens unit 70) by means of an adhesion or the like. The shape of the moving member 72 is not limited to the cylindrical shape, but may also be other regular or irregular shapes such as a rectangular cavity, as long as the lens 740 may be accommodated therein and act as a fixation for the lens 740. In this way, the moving member 72 is capable of carrying, fixing and securing the plurality of lenses 740.
As shown in FIG. 25, in some embodiments, the moving member 72 may also include two clips 722, both of which may extend in a direction parallel to the optical axis A3 of the lens assembly 70. The plurality of lenses 740 are sandwiched between the two clips 722 and spaced along the moving direction of the moving member 72. A number of the clips 722 is not limited to two, but may be three, four, etc., according to actual requirements, to make the fixation of the lens 740 by the moving member 72 more stable. The specific number is not limited herein. It should be noted that the clip 722 further reduces a weight of the moving member 72, thereby reducing a power required to drive the moving member 72 by the third drive mechanism 76. Moreover, the clip-shaped moving element 72 is less difficult to produce, thereby reducing a production cost of the first camera module 100.
The third drive mechanism 76 is similar to the first drive mechanism 52 and the second drive mechanism 54 described above, and may be one or more of an electromagnetic drive mechanism, a piezoelectric drive mechanism, or a memory alloy drive mechanism, and the like. Specifically, the third drive mechanism 76 includes a coil (not shown) disposed on the first side wall 140 of the fixing member 10 and a magnet (not shown) disposed on the moving member 72. In this way, when the coil is energized, the magnet undergo a movement to drive the moving member 72 to move the lens unit 74 along the optical axis A3 of the lens assembly 70.
It should be noted that in the embodiments, the number of lens unit 74, the moving member 72, and the third drive mechanism 76 are all one. The third drive mechanism 76 may drive the moving member 72 to simultaneously move all of the lenses 740 in the lens units 74 in the direction of the optical axis A3 of the lens assembly 70, thereby enabling the focusing of the first camera module 100.
In some embodiments, as shown in FIG. 26, the number of lens units 74, moving members 72, and third drive mechanisms 76 may each be multiple. Each lens unit 74 includes the lens 740, and is fixedly connected to the moving member 72. Each third drive mechanism 76 is connected to the moving member 72 to drive the moving member 72 independently. One or more third drive mechanisms 76 may be controlled as required to drive corresponding one or more moving members 72, thereby driving the one or more corresponding lens units 74 to move to change the overall focal length of the lens assembly 70 and thus achieve the zoom function of the first camera module 100.
Further, the image sensor 80 is arranged on a side of the lens assembly 70 away from the rotating member 20 to receive and sense the light transmitted through the lens assembly 70. Specifically, the image sensor 80 may be employed with a complementary metal oxide semiconductor (CMOS) sensor element or a charge-coupled device (CCD) sensor element.
As shown in FIGS. 5 and 27 to 28, the second camera module 300 may include a shell 302 and an imaging assembly 304 disposed within the shell 302. The shell 302 is defined with an incident hole 302 a corresponding to the imaging assembly 304, such that the external light may enter the second camera module 300 through the incident hole 302 a.
Further, a side of the decorating member 700 surrounds an outer circumference of the light inlet 13 a of the first camera module 100, and the other side may protrude from a surface of the rear cover 204 to improve an appearance of the camera module 600 by setting the shape, color, etc. of the decorating member 700 to act as a decorating role. The decorating member 700 may be made of plastic, ceramic, metal, alloy, or a composite material of metal and ceramic, such as stainless steel, aluminum alloy, and the like, and further may be polished to form a glossy surface to make the decorating member 700 more aesthetically pleasing.
Specifically, the decorating member 700 may include a main body portion 702 and a convex edge 704 that are connected to the main body portion 702.
The main body portion 702 is defined with a first through hole 702 a and a second through hole 702 b that are spaced side by side. The first through hole 702 a corresponds to the light inlet 13 a of the first camera module 100, and the second through hole 702 b corresponds to the incident hole 302 a of the second camera module 300, such that the first camera module 100 and the second camera module 300 may collect external light through the corresponding through hole, respectively. Specifically, the first through hole 702 a may be a substantially square hole and the second through hole 702 b may be a substantially round hole.
Of course, the structure of the main body portion 702 is not limited to the above description. For example, the first through hole 702 a and the second through hole 702 b may also be a connected through hole through which the first camera module 100 and the second camera module 300 both capture and collect external light. Moreover, the first through hole 702 a and the second through hole 702 b may be of other shapes, such as both may be square or round. Configurations shall depend on the actual needs and the shape of the light inlet 13 a of the first camera module 100 and the incident hole 302 a of the second camera module 300.
Further, the convex edge 704 is connected and arranged on a side of the main body portion 702 facing an interior of the mobile phone, and extending in a direction away from the first through hole 702 a and the second through hole 702 b. The groove 13 b of the fixing member 10 matches the shape of a side of the convex edge 704 near the light inlet 13 a, such that the decorating member 700 is fixed to the fixing member 10 by accommodating a part of the structure of the convex edge 704. In this way, the decorating member 700 is able to partially snap into the recess 13 b in the direction of the first axis A1 to reduce the size of the camera assembly 600 in this direction, making the structure more compact and facilitating the miniaturization of the camera assembly 600 and the electronic device. It should be noted that the embodiments do not limit the specific structure and shape of the recess 13 b, as long as the recess 13 b can be matched with the decorating member 700 to reduce the size of the camera assembly 600 in the direction of the first axis A1.
Further, as shown in FIG. 29, in the related art, the recess 13 b for accommodating part of the structure of the decorating member 700 may be omitted on the fixing member 10 to make the overall thickness of the electronic device smaller. The fixing member 10 extends at least partially into the decorating member 700 in the direction of the second axis A2 (as shown in FIG. 7), such that the decorating member 700 may cover a periphery of the fixing member 10 in the direction of the second axis A2. Since the first camera module 100 is a periscopic camera module, and a width of the first camera module 100 in the direction of the second axis A2 is larger than that of vertical imaging modules, the decorating member 700 is required to be configured with a larger size, which is detrimental to the aesthetics of the electronic device as well as to the thinness and miniaturization of the same.
The decorating member 700 may be an integrated structure formed by cutting, etc. The main body portion 702 and the convex edge 704 are two parts of the decorating member 700, respectively. Of course, the main body portion 702 and the convex edge 704 may also be a split structure, i.e., the main body portion 702 and the convex edge 704 are two independent components, which are assembled together by welding, adhesion, etc., to form the decorating member 700, which is not specifically limited herein.
Further, as shown in FIGS. 2 and 3, the rear cover 204 of the mobile phone is defined with a light-transmitting hole 204 a corresponding to the camera assembly 600. A side of the convex edge 704 is fixed to the fixing member 10 and the other side is abutted against an inner surface of the rear cover 204 around the light-transmitting hole 204 a. The main body portion 702 is inserted into the light-transmitting hole 204 a, or further extends out from the light-transmitting hole 204 a. In this way, the convex edge 704 may serve as a restriction on the position of the decorating member 700, such that the decorating member 700 may not move out of the housing 200. In addition, the decorating member 700 may be further fixed to the rear cover 204 by applying adhesive between the decorating member 700 and the rear cover 204, or the decorating member 700 may also be firmly fixed to the rear cover 204 by the interference fit between the main body portion 702 and the light-transmitting hole 204 a.
It should be noted that the convex edge 704 is not a necessary structure. In some embodiments, the decorating member 700 includes only the above-mentioned main body portion 702. A side of the main body portion 702 is accommodated in the groove 13 b of the fixing member 10 and fixed to the fixing member 10. The other side is inserted in the light-transmitting hole 204 a of the rear cover 204 of the mobile phone, or extends further out of the light-transmitting hole 204 a.
As shown in FIGS. 5 and 27, the bracket 900 is disposed at a periphery of the first camera module 100 and that of the second camera module 300, and is fixedly connected to the first camera module 100 and the second camera module 300. The decorating member 700 is disposed on a side of the bracket 900 and abutted against the same such that the convex edge 704 of the decorating member 700 may cover an edge of a side of the bracket 900 facing the decorating member 700. Or, the bracket 900 may also be spaced apart from the decorating member 700. In this way, the bracket 900 may protect the first camera module 100 and the second camera module 300 to reduce an impact on the first camera module 100 and the second camera module 300, thereby increasing a service life of both.
Further, as shown in FIGS. 30 to 36, the present disclosure also provides a shooting method embodiment. In the embodiments, the camera may be configured as the first camera module 100 in the above-mentioned electronic device, of which the related structure is described above and will not be repeated herein. Specifically, the shooting method may include operations at blocks illustrated in FIG. 30.
At block M10: A shaking parameter of the fixing member 10 is detected and obtained, and a control signal corresponding to the shaking parameter is generated; and
At block M20: A control signal is configured to drive the rotating member 20 to rotate around the first axis A1 relative to the fixing member 10 via the first ball 32, and around the second axis A2 relative to the fixing member 10 via the second ball 34.
A gyroscope or an accelerometer, etc. may be installed. During the process of shooting by the first camera module 100, a shaking of the fixing member 10 may be monitored, analyzed and processed to obtain the shaking parameter.
Specifically, the shaking parameter may be a displacement of the fixing member 10 in a certain direction or a rotation angle around a certain axis during the shooting process. For example, the shaking parameter may be a rotation angle of the fixing member 10 around the first axis A1, a rotation angle around the second axis A2, or other parameters. The first axis A1 and the second axis A2 may be configured perpendicular to each other.
The control signal is derived from an analysis of the shaking parameter and corresponds to an action to be performed by the rotating member 20. To a certain extent, the control signal is “opposite” to the shaking parameter, such that the rotating member 20 may rotate in an opposite direction of the shaking of the fixing member 10 to compensate for an incidence deviation of the incident light entering through the light inlet 13 a due to the shaking of the fixing member 10, and to avoid or reduce the adverse effect on the imaging caused by the shaking of the mobile phone.
Further, block M10 may include operations at blocks illustrated in FIG. 31.
At block M12: An angle of rotation of the fixing member 10 around the first axis A1 and an angle of rotation of the fixing member 10 around the second axis A2 are detected and obtained; and
At block M14: A first control signal corresponding to the angle of rotation of the fixing member 10 around the first axis A1, and a second control signal corresponding to the angle of rotation of the fixing member 10 around the second axis A2 are generated.
Accordingly, block M20 may include operations as followed.
At block M22: The first control signal is configured to drive the rotating member 20 to rotate a first angle compensation amount via the first ball 32 relative to the fixing member 10 around the first axis A1; and
At block M24: The second control signal is configured to drive the rotating member 20 to rotate a second angle compensation amount via the second ball 34 relative to the fixing member 10 around the second axis A2.
The angular compensation amount of the rotating member 20 is opposite to the shaking parameter of the fixing member 10. Specifically, when the fixing member 10 rotates a first angle in a clockwise direction around the first axis A1, then the first angle compensation amount is the first angle of rotation of the rotating member 20 around the first axis A1 in a counterclockwise direction. Similarly, when the fixing member 10 rotates the second angle in a clockwise direction around the second axis A2, then the second angle compensation amount is the second angle of rotation of the rotating member 20 around the second axis A2 in a counterclockwise direction. It should be understood that the terms of “clockwise” and “counterclockwise” are not to be construed as a limitation of the present disclosure.
In practice, there may be cases where the first and/or second control signals are empty. For example, in cases of the angle of rotation of the fixing member 10 around the first axis A1 is detected to be zero, the fixing member 10 is determined not to rotate around the first axis A1, and the rotating member 20 is not required to rotate around the first axis A1 for compensating. The corresponding first control signal is null, i.e., the rotating member 20 is not required to be controlled to rotate around the first axis A1. Of course, in cases where the angle of rotation of the fixing member 10 around the first axis A1 and the angle of rotation around the second axis A2 are detected to be zero, the first control signal and the second control signal are both empty, such that the rotating member 20 is not required to be controlled to rotate around the first axis A1 and the second axis A2.
Further, the first camera module 100 includes the first drive mechanism 52 and the second drive mechanism 54. Both the first drive mechanism 52 and the second drive mechanism 54 are connected to the base 22. Block M20 may include operations at blocks illustrated in FIG. 32.
At block M26: The first control signal is configured to control the first drive mechanism 52 to drive the rotating member 20 to rotate the first angle compensation amount via the first ball 32 relative to the fixing member 10 around the first axis A1; and
At block M28: The second control signal is configured to control the second drive mechanism 54 to drive the rotating member 20 to rotate the second angle compensation amount via the second ball 34 relative to the fixing member 10 around the second axis A2.
Specifically, the first drive mechanism 52 may include the first coil 522 and the first magnet 520. Block M26 may include operations at blocks illustrated in FIG. 33.
At block M262: A first current with a first direction and a first magnitude is input to the first coil 522 based on the first control signal to generate a magnetic field in the first coil 522; and
At block M264: The first magnet 520 moves under an action of the magnetic field generated by the first coil 522 to drive the base 22 for driving the light redirecting member 24 to rotate the first angle compensation amount via the first ball 32 relative to the fixing member 10 around the first axis A1.
According to electromagnetic induction, directions as well as the magnitudes of the current input in the first coil 522 affects the rotation of the first magnet 520 therein. Specifically, the first direction of the first current determines the moving direction of the first magnet 520, and thus the rotating direction of the rotating member 20 around the first axis A1. The first magnitude of the first current affects the angle of rotation of the first magnet 520 around the first axis A1. Therefore, the first direction and the first magnitude of the first current through the first coil 522 are required to be determined based on the first control signal to control the direction and angle of rotation of the rotating member 20 around the first axis A1.
Specifically, the first drive mechanism 52 may also include the second coil 526 and the second magnet 524. Block M26 may include operations at blocks illustrated in FIG. 34.
At block M266: A second current with a second direction and a second magnitude is input to the second coil 526 based on the first control signal to generate a magnetic field in the second coil 526; and
At block M268: The second magnet 524 moves under an action of the magnetic field generated by the second coil 526 to drive the base 22 for driving the light redirecting member 24 to rotate the second angle compensation amount via the first ball 32 relative to the fixing member 10 around the first axis A1.
The current input to the second coil 526 based on the first control signal to drive the second magnet 524 herein is similar to the first coil 522 and the first magnet 520 described above and will not be repeated herein.
It should be noted that the first control signal may control only one pair of the first coil 522 and the first magnet 520, and the second coil 526 and the second magnet 524, to drive the base 22 to rotate. Or, the first control signal may also control the above two pairs of driving base 22 to rotate cooperatively at the same time, which can be configured according to actual needs and is not limited herein.
The second drive mechanism 54 may include the third coil 542 and the third magnet 540. Block M28 may include operations at blocks illustrated in FIG. 35.
At block M282: A third current with a third direction and a third magnitude is input to the third coil 542 based on the second control signal to generate a magnetic field in the third coil 542; and
At block M284: The third magnet 540 moves under an action of the magnetic field generated by the third coil 542 to drive the base 22 cooperatively with the second magnet 524 for driving the light redirecting member 24 to rotate the second angle compensation amount via the second ball 34 relative to the fixing member 10 around the second axis A2.
The current input to the third coil 542 based on the second control signal to drive the second magnet 524 is similar to the first coil 522 and the first magnet 520 described above and will not be repeated herein.
It can be understood that the first camera module 100 also includes the lens assembly 70 and the third drive mechanism 76. The lens assembly 70 is movably connected to the fixing member 10 under the drive of the third drive mechanism 76 for transmitting light redirected by the light redirecting member 24. Specifically, the lens assembly 70 is movably disposed along the direction of the optical axis A3 of the lens assembly 70. The optical axis A3 of the lens assembly 70 is perpendicular to the first axis A1 and the second axis A2. The above shooting method may also include operations at blocks illustrated in FIG. 36.
At block M30: A displacement of the fixing member 10 in the direction of the optical axis A3 of the lens assembly 70 is detected and obtained;
At block M40: A third control signal corresponding to the displacement of the fixing member 10 in the direction of the optical axis A3 is generated; and
At block M50: The third control signal configured to control the third drive mechanism 76 to drive the lens assembly 70 to move a displacement compensation amount along the optical axis A3 of the lens assembly 70.
Similar to the above-mentioned embodiments, the displacement of the fixing member 10 in the direction of the optical axis A3 of the lens assembly 70 may also be detected by a gyroscope or an accelerometer or the like.
The displacement compensation amount is opposite to the detected displacement of the fixing member 10 in the direction of the optical axis A3 of the lens assembly 70. For example, after the fixing member 10 is detected to have performed a displacement in a B direction along the optical axis A3, the third control signal may be configured to control the third drive mechanism 76 to drive the lens assembly 70 to move an equal displacement in a direction opposite to the B direction along the optical axis A3, thereby compensating for the incidence deviation of the incident light entering from the light inlet 13 a due to the movement of the fixing member 10 in the direction of the optical axis A3 of the lens assembly 70.
In the embodiments, during the process of taking pictures, the rotation of the fixing member 10 around the first axis A1, the rotation of the fixing member 10 around the second axis A2, or the movement of the fixing member 10 in the direction of the optical axis A3 of the lens assembly 70 may be detected to drive the base 22 for driving the optical redirecting member 24 to make a corresponding compensation movement. In this way, the incidence deviation of the incident light entering from the light inlet 13 a due to the shaking of the fixing member 10 may be compensated, and thus avoid or reduce the deviation of the incident light that adversely affects the image quality of the camera.
As shown in FIG. 37, FIG. 37 is a structural schematic view of a camera component 600 according to a first embodiment of the present disclosure. The camera assembly 600 further includes a third camera module 500. Specifically, the first camera module 100, the second camera module 300, and the third camera module 500 are arranged side by side. Further, in some embodiments, the first camera module 100, the second camera module 300, and the third camera module 500 may be spaced apart, and two adjacent camera modules may also be abutted against each other. In other embodiments, the first camera module 100, the second camera module 300, and the third camera module 500 are an integrated module. In some embodiments, a shape formed by the three camera modules is either substantially monolithic, as shown in FIG. 37, or substantially L-shaped, as shown in FIG. 38, which will be explained below by specific embodiments referring to the accompanying drawings.
In some embodiments, the first camera module 100 is a periscopic telephoto camera, the second camera module 300 is a large wide-angle camera, and the third camera module 500 is a wide-angle main camera. Specifically, an angle of view of the periscopic telephoto camera is in the range of 10 to 30 degrees, i.e., the first camera module 100 has a small angle of view. Therefore, the first camera module 100 has a large focal length, which is generally applied for filming a distant scene to obtain a clear image of the distant scene. The focal length is larger in cases of distant shooting. Compared to the vertical lens module, the first camera module 100 of the present disclosure is arranged with the periscopic lens module of a smaller height, thereby reducing the overall thickness of the camera module 600. The vertical lens module refers to the lens module having a straight optical axis, or to say, the incident light is conducted along a direction of a straight optical axis to photoreceptors of the camera module.
Specifically, the large wide-angle camera, i.e., the second camera module 300, has an extra-large wide-angle of view in the range of 110 to 130 degrees for wide-angle shooting, such that the optical zoom magnification may be increased. The second camera module 300 has a larger angle of view and a shorter focal length correspondingly, such that the second camera module 300 is generally applied for close-up shooting to obtain local close-up images of objects.
The wide-angle main camera, i.e., the third camera module 500, has a normal angle of view in the range of 80 to 110 degrees. The wide-angle main camera may have large number of pixels and large pixels, and is not applied for distant or close-up scenes, but for normal shooting of objects.
The present disclosure may obtain image effects such as background blurring, local sharpening of pictures, etc. by a combination of the first camera module 100, the second camera module 300, and the third camera module 500.
Specifically, in some embodiments, for example, the angle of view of the first camera module 100 may be 10 degrees, 12 degrees, 15 degrees, 20 degrees, 26 degrees, or 30 degrees, and so on. The angle of view of the second camera module 300 may be 110 degrees, 112 degrees, 118 degrees, 120 degrees, 125 degrees, or 130 degrees, and so on. The angle of view of the third camera module 500 may be 80 degrees, 85 degrees, 90 degrees, 100 degrees, 105 degrees, or 110 degrees, and so on.
As described above, due to the factor of angle of view of the first camera module 100 and the third camera module 500, the first camera module 100 and the third camera module 500 are arranged with an optical stabilization device to enable the first camera module 100 and the third camera module 500 to obtain a better quality image. The optical stabilization device is generally configured with one or more magnetic elements, such as the first magnet and the second magnet described above, and will not be repeated herein. Therefore, the magnetic elements on the first camera module 100 and the third camera module 500 generate magnetic fields for each other. Understandably, if the first camera module 100 and the third camera module 500 are too close together, the magnetic force generated between the magnet on the first camera module 100 and the magnetic element on the third camera module 500 may inevitably have an impact on the focusing process of the first camera module 100 or the third camera module 500 taking pictures, affecting the image quality. In some embodiments, since the large wide-angle camera (i.e., the second camera module 300) has functions of autofocus (AF) or fixed-focus (FF), the second camera module 300 is arranged between the first camera module 100 and the third camera module 500, i.e., between the periscope telephoto camera and the wide-angle main camera. In this way, an overall space formed by the three camera modules may be reduced, and an interference of the magnetic components between the first camera module 100 and the third camera module 500 may be limited.
As shown in FIGS. 38 and 39, FIG. 38 is a structural schematic view of a camera component 600 according to a second embodiment of the present disclosure, and FIG. 39 is a structural schematic view of an electronic device according to a first embodiment of the present disclosure. In some embodiments, the light redirecting member 24 has a first center point 248, the second camera module 300 has a second center point 302, and the third camera module 500 has a third center point 502. The first center point 248, the second center point 302 and the third center point 502 are in a straight line and perpendicular to the optical axis A3 of the lens assembly 70. It should be understood that the first center point 248, the second center point 302 and the third center point 502 being in a straight line means that front projection points of the first center point 248, the second center point 302, and the third center point 502 on the rear cover 204 are in a straight line. That is, when light is directed from the front of the mobile phone to the rear cover 204 and perpendicular to the rear cover 204, the projection points of the first center point 248, the second center point 302, and the third center point 502 are located on the rear cover 204 in a straight line.
Specifically, when the first center point 248, the second center point 302 and the third center point 502 are in a straight line and perpendicular to the optical axis A3 of the lens assembly 70, the length of the first camera module 100 along the optical axis A3 of the lens assembly 70 is larger than the length of the second camera module 300, as shown in FIG. 38. That is, the length of the front projection of the first camera module 100 on the rear cover 204 is larger than the length of the front projection of the second camera module 300 and the third camera module 500 on the rear cover 204. The first camera module 100 is a telephoto periscope camera including the light redirecting member 24, the lens assembly 70, and the image sensor 80. The light path formed by the light redirecting member 24, the lens assembly 70, and the image sensor 80 is not a straight line and required to be redirected for transmission. A certain distance is required to be configured between the three. While the optical path formed by the second camera module 300 or the third camera module 500 during the shooting process is a straight line. In this way, the length of the first lens module 100 is larger than either the second camera module 300 or the third camera module 500.
In some embodiments, the second camera module 300 and the third camera module 500 have equal lengths along the optical axis A3 of the lens assembly 70. It should be understood that the three camera modules are arranged in such a structure with an L-shaped configuration in appearance, such that a more aesthetically pleasing integration formed by the three camera modules may be achieved.
In some embodiments, the second camera module 300 and the third camera module 500 have unequal lengths along the optical axis A3 of the lens assembly 70. For example, the lengths of the three camera modules may increase progressively along the optical axis A3 of the lens assembly 70, as shown in FIG. 40; or decrease progressively, as shown in FIG. 41, which is not specifically limited herein.
In some embodiments, the first center point 248, the second center point 302 and the third center point 502 are in a straight line and parallel to the optical axis A3 of the lens assembly 70. That is, the three camera modules are disposed in a line in appearance, as shown in FIGS. 37 and 42. It should be understood that in embodiments in which the three camera modules are disposed in a line and the second camera module 300 is disposed between the first camera module 100 and the third camera module 500, the light redirecting member 24 may be closer to the third camera module 500 relative to the lens assembly 70 in some embodiments. In another embodiments, the lens assembly 70 may also be closer to the third camera module 500 relative to the light redirecting member 24, as shown in FIG. 43, which is not specifically limited herein.
As shown in FIG. 44 and FIG. 45, wherein FIG. 44 is a structural schematic view of a housing 200 according to an embodiment of the present disclosure, and FIG. 45 is a structural schematic view of an electronic device according to a second embodiment of the present disclosure. The following describes the position and connection relationship between the three camera modules and the housing 200. In some embodiments, the housing 200 is defined with three openings. Center points of the three openings are disposed in a straight line. Specifically, the three openings are arranged on the rear cover 204 of the housing 200, including a first opening 204 a, a second opening 204 b, and a third opening 204 c. A connecting rib is formed between the first opening 204 a, second opening 204 b, and third opening 204 c, i.e., the three openings on the rear cover 204 are spaced apart. Further, the first camera module 100 is installed correspondingly at the first opening 204 a, the second camera module 300 is installed correspondingly at the second opening 204 b, and the third camera module 500 is installed correspondingly at the third opening 204 c. Specifically, the light redirecting member 24 of the first camera module 100 is facing the first opening 204 a for receiving light. The front projection of the light redirecting member 24 falls on the first opening 204 a. It is understood that the front projection of the light redirecting member 24 described herein is a projection produced by the light redirecting member 24 when light is shone from the front of the mobile phone in a direction toward the rear cover 204.

Specifically, a length of the first edge 201 may be larger than that of the second edge 203. That is, the first edge 201 is a long edge of the rear cover 204 and the second edge 203 is a short edge of the rear cover 204.
Alternatively, in different embodiments, a connecting line of center points of the first opening 204 a, the second opening 204 b, and the third opening 204 c is parallel to the first edge 201 or the second edge 203.
In some embodiments, as shown in FIG. 45, the connecting line of center points of the first opening 204 a, the second opening 204 b, and the third opening 204 c is parallel to the first edge 201. That is, the three camera modules are in a substantially L-shaped structure.
In other embodiments, as shown in FIG. 46, the connecting line of center points of the first opening 204 a, the second opening 204 b, and the third opening 204 c is parallel to the second edge 203. That is, the three camera modules are disposed in a line.
As shown in FIG. 47, specifically, the rear cover 204 includes a rear cover center point 2042, a center line 2044 configured to be a center line passing through the rear cover center point 2042 and parallel to the first edge 201, and a center line 2046 configured to be a center line passing through the rear cover center point 2042 and parallel to the second edge 203. The first opening 204 a, the second opening 204 b and the third opening 204 c are disposed between the second edge 203 and the second center line 2046. That is, the three openings on the rear cover 204 are disposed in an upper half of the mobile phone. Further, in some embodiments, a connecting line of the center points of the first opening 204 a, the second opening 204 b, and the third opening 204 c coincides with the first center line 2044 of the rear cover 204. That is, the first camera assembly 600 is disposed in the middle of the upper half of the mobile phone. It should be understood that the first camera assembly 600 being disposed in the middle of the upper half of the mobile phone facilitates a stacking of the entire structure and achieve a more aesthetically pleasing appearance of the entire mobile phone.
